Intravascular Lithotripsy Is Associated With Superior Clinical Outcomes Compared to Atherectomy: A Large‐Scale, Propensity‐Matched Analysis

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary artery disease (CAD) with severe calcification remains a growing challenge in percutaneous coronary intervention (PCI). Atherectomy (ATH) has long been used for plaque modification, whereas intravascular lithotripsy (IVL) has emerged as a promising alternative. Large‐scale comparative data on long‐term outcomes are limited.

Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

Annular Ellipticity and Sizing Strategy in Transcatheter Aortic Valve Implantation: Independent or Combined Risk Patterns?

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Elliptical annular anatomy has been considered a risk factor for adverse outcomes after TAVI, particularly paravalvular leakage (PVL). Prosthesis oversizing is thought to improve sealing, but the interaction between annular shape and sizing strategy remains unclear.

Excessive Ostial Stent Protrusion: Evaluation of Management Strategies and Clinical Outcomes of the Side Flap Technique

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Backgrounds Accurate stent positioning in aorto‐ostial lesions remains challenging due to complex three‐dimensional anatomy, lack of optimal fluoroscopic projections, and high rates of geographic miss. Stent overhang impairs guide catheter re‐engagement and complicates future revascularization.

Mitral Transcatheter Edge‐to‐Edge Repair in Patients With Advanced Heart Failure: A Single‐Center Experience and Insights Into Anatomical and Clinical Determinants of Procedural Complexity

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Advanced heart failure (HF) remains a clinical challenge, and mitral transcatheter edge‐to‐edge repair (M‐TEER) has emerged as a potential bridging strategy. Aims To describe the clinical outcomes of M‐TEER in a single‐center cohort of patients with advanced HF and to identify anatomical and clinical features potentially associated ...

Design of Steel Column Base Connections for Large Eccentricities

open access: yes, 2013
In this paper, the concrete underneath the base plate together with the base plate is referred to as “component concrete in compression and base plate in bending” or in short “concrete in compression”. The strength of the concrete in compression depends on the concrete base material, the behaviour of the grout layer and the complex phenomena in the ...
